Password with Listen Mode

Post by yatar »

Before with 1.0.8.5, the user connect with the listen mode, i change the shortcut with the command -connect and it's works.

But now with 1.0.9.5, it's works but i must type the password, and with 1.0.8.5 no password requiere with listen mode.

Sorry for my english

yatar

what is your command line for -connect with vncviewer or winvnc or both ?

maybe missing the key in case of encryption usage ?

ok, i think i understand
can't success

maybe you had copy winvnc.exe and vncviewer from shared folder.
download uvnc1095.zip to your computer on local folder and then direct extract at the place of your ultravnc installed on local hard drive.

ipv4 is the hostname of computer, correct ?
"C:\Program Files\UltraVNC\winvnc.exe" -connect hostname

winvnc -connect localhost
for test on same computer, not possible with actual value
see the error at ultravnc.ini
AllowLoopback=0 <-- change value to 1

maybe you could do a capture of your strange password request should not exist.

what is your CPU AMD or Intel ?

it simple.... sorry for long time diagnostic...

success
"C:\Program Files\UltraVNC\winvnc.exe" -connect localhost -run

fail, happen nothing and no password request.
"C:\Program Files\UltraVNC\winvnc.exe" -connect localhost
(winvnc just open and close immediately)

tested with limited account, i can't reproduce your vnc password request !

I am seeing the same issue as yatar.

UVNC 1.0.9.5 server on WinXP, right click the tray icon, add new client, enter hostname and hit OK


VncViewer in -listen mode on any machine (tested Win7, Vista, and XP), prompted for the Authentication password. This happens with 1.0.2 and 1.0.8.2

With the 1.0.9.5 version of the viewer, it does not ask for a password

*Edit*: forgot to mention that there are no plugins specified on the viewer or the server.
